' This application is a division of my for: mer application filedSeptember 1st, 1908.

Ser. No. 451,161.

The object of my invention is to provide a car of this class in whichthe doors are so arranged that attherear end of the car, the regularentrance door will operate so'as to permit passengers to enter the car,but not to leave the car, and the doors at the other end will permit thepassengers to leave the car,

"and when the car is run in the opposite dimotion, the doors can be madeto operate in thereverse manner, that is, the rear door which was thefront door, will operate so as to admit passengers and the other doorwill operate'soas to permit the egress of passengers.

For a more particular description of my "invention, reference is to behad to the accompanyin drawings forming a part hereof, in whic Figure 1is an end elevation of a portion of a car provided with my improvements.Fig. 2 is a sectional view of the same. Fig. 3 is a plan V ew of aportion of my improved car with parts broken away to show theconstruction. I

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

One embodiment of my invention is shown in the accompanying drawings. Inthis structure the door 3 is comprised of two curved sections 116 and117 respectively, each oi which covers about 90 and these sections" areseparated by open space of about 90'and at their tops they are connectedby a disk 118 which holds them in rigid relation. -At their bottom endthey are provided with pintles either with or without rollers which movein the circular pintle groove 119 cut in the floor of the car. This disk118 is provided with a pivot 120 so that it will revolve true andconcentric. With this pivot 120 are two ratchets 121 and 122respectively, having teeth facing in op- Specification of LettersPatent.

Divided and this application filed December posite directions, whichteeth are engaged by suitable pawls 123 and 124: either of which may berendered inoperative by means of a rocker 125 sothat the door may 'berotated in either direction as desired, ac-

cording to which pawl is made operative. The rocker 125 may be shiftedby any suitable means as a bar 126.

A cash register may be suitably mounted adjacent to the door andconnected therewith so that it will register one fare for each 180 thatthe door turns. The car in which this door is placed is provided with apartition 127 which separates the seat 128 from the sections 116 and 117and this revolving door protrudes through the doorway of the car betweenthe stanchions 129 and upright 130, the step 131 being slightly curvedoutwardly LO permit of this construction. Handles 132 are provided bymeans of which the door may be turned. It is operated as follows:Assuming the parts to be as shown in the drawings, the handle 132 isgrasped and shoved to the right thereby bringing an open space oppositethe doorway. Through this the passenger enters and continues shoving thedoor to the right until the open space is in front of him when he entersthe car. In entering he has turned the door 180, first 90 to get betweenthe panels and then 90 to get out from between them. hen the door isused for exit purposes the operation is substantially the same as abovedescribed, except that it is preterably turned in the opposite directionand then the door would normally have a panel between the partition 127and the upright 130.

While I have shown and described one embodiment of my invention, it isevident that it is not restricted thereto but is broad enough to coverall structures that come within the scope of the annexed claims.

What I claim is:

1. In a car of the class described, a door comprising two panels held infixed relation with a space between them sufficient for a passenger,means for mounting said panels so that they rotate about a common axis,a partition adjacent to said panels and two posts parallel to saidpartition and adjacent to one of said panels when the door is in itsclosed osition.

2. In a car 0 the class described, a partition and posts parallelthereto, a floor, a ceiling, a pair of parallel panels fixedto a diskrevolving in said ceiling and separated sufiiciently to let a passengerpass betweenthem and means for mountingsaid disk so that it can revolveabove the axis of said panels.

3. In-a car of the class described, a floor with a circular groovetherein, a ceiling, a

partition and posts extending between said floor and ceiling, a disk andmeans for mounting the same so that it will revolve in said ceiling,curved panelssnspended from said disk .and means for guiding the lowerends of the panels said circular means for mounting the same so that itwill revolve in said ceiling, a door composed of two curved panelssuspended from said disk and means in said floor for guiding the lowerends of said panels.

5. In a car of the class described, a parti tion and posts parallelthereto, a floorjand a ceiling uniting said 'posts,an annular groovepartition, a door suspended from said disk having its lower ends guidedby said groove, means for pivotally mounting said disk so that it isfree to revolve and means for per-- in said floor and a disk mounted insaid mitting said disk to revolve in one direction only.
